Raspberry Pi 4 Model B (4GB) Smart-home IoT Hub Kit

The Raspberry Pi 4 Model B (4GB) Smart-home IoT Hub Kit is a project-ready platform built around the Raspberry Pi 4 Model B (4GB) (64-bit ARM). It pairs the board with 24 matched components — sensors, drivers, displays and power — so you spend your time engineering, not chasing missing parts.

What you'll build

Work through 8 guided projects (20-30 hours, difficulty: Intermediate-Advanced). With this kit you'll connect to Wi-Fi, read environmental sensors, and push live data to the cloud or your phone — each project building on the last, with code, wiring diagrams and clear explanations in the included guide.
